What I notice first is that your triangles get sunshine. To give some instant parent-pleasing impact, why not start off with some summer bedding? Weed out all the low-growing vegetation with a fork and then prepare the soil by digging it over and adding some organic matter. Tread the air pockets down and rake it smooth. Plant petunias, marigolds, lobelias etc. You can get these in bulk on special offer at this time of year. Because your beds are so small you'll be able to water them with a watering can. Unfortunately summer bedding is quite thirsty. Alternatively sow annuals it's cheaper and will require less watering.
In the autumn come back to the forum and ask what to plant for winter!
